Point Locus Wearable GPS PathFinder System is designed as way finding aid for the visually impaired as they travel outdoors. This system will take advantage of one of the most important senses for visually impaired users: touch. The goal is to design a product that improves the lifestyles of visually impaired people in a meaningful way. It needs to be something practical that complements their natural adaptations to their disability and extends their limitations. It will be a cost effective solution that improves their way finding ability, making them much more independent when traveling.

Wearable GPS PathFinder for Visually Impaired (Bind) People NavigationPoint Locus Wearable GPS PathFinder system communicates a language of vibrations to the user to guide them. The vibration comes from two vibrating pager motors located on the users triceps. Whenever they need to turn, whichever vibrator is closest to the turn angle will vibrate. Then, the user stops and rotates in that direction, until they feel the vibration from both vibrators. This indicates the user is facing the right direction and should move forward. This signal is repeated every 20 seconds as a reassurance to the user that they are going in the right direction and should continue forward. When a destination is reached, a sustained vibration from both vibrators of 5 seconds indicates this.

Point Locus Wearable GPS PathFinder system will take GPS location data and use the current location of the user, and the desired destination to form a path from one point to the other. This information will be used by a microcontroller to control the vibrator circuits, so they vibrate at the proper time.

By using the sense of touch, rather than audio, the system does not overload one vital sense that is needed as an adapted way to orient oneself. It also does not require vision to put on and adjust to the right size, because Velcro allows a person to feel out the proper place to attach the straps.
